Young Thug is hip-hop's most reliably unpredictable artist. On "About the Money", he offers a new flow template, pushing T.I. to modernise his rap style for the occasion. Tyga's "Hookah" clicks due in large part to Thug's unforgettable, barely sung hook melody. But the understated, smooth effervescence of his tag-team with Rich Homie Quan on Rich Gang's "Lifestyle" epitomises Thug's force of character and unorthodox talents.
